TABLE AND ENDLESS CONVEYER Filed May 10, 1932 2 Sheets-Sheet 2 Inventor lz'a' Bonn 21720 A tlorney 2 5 cate like parts.

Patented Apr. 2, 1935 I object of this inizention is to provide a t b with n en l c ve a a pa t t er f.;

the-endless conveyerbeing adapted to carry products from one end of the table to the other, or from the kitchen to the table, or from the kitchen throughout the length of the table.

Another object is to provide an endless conveyer that will carry products out and return without upsettingor spilling them. I These and other objects of-the invention will be illustrated in the drawings, described in the specification, and pointed out in theend thereof. I h

lnthe drawings: 1 1 Figure'l is atop plan view of the table. Figure; is a vertical section through the table on the, line 22: 20: of Figure -1. 7

Figure ,3 isa' vertical, =section ,on the line 3x33: of Figure l.

Figure l is a vertical section on-the-linefia: 4r; ofFigur-e 2.

Figure 5 is a detail view of an elevator-provided at one end of the table fora special purpose.

In the ,drawmgs. like reference numerals indi- In the drawings, reference numeral I indicates the .tahle top, and 2, 3, and 4 indicate-thetable legs or supports. Theselegs are preferably'of metal bars and are bent outwardly at the bflttom to form f eet 6, and .are bent outwardly at the t p to. rormbracke 1 on whic h table ops I, I maybe attached. The legs or uprights are spacedapart by the ,braces or floors 8 and 9, each of which is in the shape of a pan which extends the whole length of the table. On the outside of the legs are fastened the upright cover plates Ill and I I, which protect the moving parts from interference from either side.

At the top of the table on each side are provided the channel-shaped runways or tracks I2 and I3, and below them are provided the L-shaped runways or tracks I4 and I5. At each end of the table are placed shafts I6, I6 and I1, I! on which are carried sprocket wheels I8 and I9, on which travel the endless sprocket chains 20 and 2|.

At suitable intervals are provided carriers of diiferent shapes and sizes, such as are shown at 22, 23, 24 and 25. These carriersare made and supported so that by gravity they can remain in a horizontal position as they move forward or back, or up or down. Thus, as is shown in Figure 3, the carrier 24 is provided with trunnions 21 and 28, one on each side thereof, on the ends of which are carried wheels or rollers 29 and 38 that engage in and are supported by the channels I2 and the claims at runway to the upper runway.

I3 on the upper run, and by the runwaysqvliland l5 onthe lowerrun. The carrier; .24 ishowlshaped and the trunnions are attached-near the upper edge thereof, so that the carrier will rmain tain its horizontal position by gravity so long as it is tree to swing on the trunnionshoon, the chains 20 and ,21 are carried rings 'ZIIA :and 24A through which the trunnions pass and .by which the carriers are moved.

In the lower runway :I have-shown the carhier 25, which is,also provided with trunnions 21 and 28, supported by rollers 29 andtll. I

The sprocket chains :run in the direction of the arrowsshown inFigure 2. v 1

As shown in Figure 4-, bearings .35 andy36-rare' provided, which are supported: by the channels I2 and I 3. Plates 3,1- and 38 are also-provided, which are supported from-the channels ,I 2 .andlil and the runways 2M andl5. In the .bearingsd3 5 and Y36 are providedshorit shafts- I-B, It onfwhich the sprocket wheels is, (IS-arecarried, -l llach .of these shafts is drivenlzyy a pulley. 39,39,- which in turn are driven by :belts 40, which :in turn are driven from pulleys 4|, 4| carried on theL-shaftAZ which is driven bya motor 43. The operation of this deviceis as follows.,- -The, sprocket chain travelsin the direction of the arv r ws sh wn. in F u al a d the Catriers; 22, .23 and 24 move to the right along the tabletop. Whe e mme he wk t heel thwarriers follow the Tchainaround the sprocket -W;heel, andv for this purposeareguidediby the ends Qf the runways- I,2,and;I,3 which arecurvedrdown, as shown at the ends of Figure 2, and'they are also guided by the ends of the runways I4 and I 5, which are curved up to receive the oncoming carrier. It will be seen that the receiving end of the runway I 5 projects out beyond the discharge end of the runway I3 at the right of Figure 2, and the receiving end of the runway i3 projects out beyond the discharge end of the runway I5 at the left of Figure 2. This helps to transfer the oncoming container in each case as it moves from the upper runway to the lower, or from the lower 52. On the lower end of the stem is provided a 55 head 53, to which is attached a cable 54 which runs over a pulley 55. A weight 56 is provided on the lower end of the cable. The guide is carried on a bracket or cross bar 51, which is attached to the brace 9. When the carrier descends at the right hand end of the table I, I, it engages the table 50, which will at once keep it from tilting and will descend with it until it reaches the lower limit of its movement, after which the carrier'will slide off the table and will release the table so that the table will be moved up by the Weight 56.

On each end of each carrier at the bottom is provided a roller 60 which engages the floors 8 and 9 and serves to steady the position of the carrier as it moves.

For convenience, each carrier can be cut away on the ends, as indicated at 6!, 6|. This makes it easier to take hold of the pan carried therein for the purpose of removing it.
